MSP430F5249IZQE Texas Instruments 16bit MCU

MSP430F5249IZQE Overview

The TI MSP family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with extensive low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3.5 μs (typical).

The MSP430F524x series are microcontroller configurations with four 16-bit timers, a high-performance 10-bit ADC, two USCIs, a hardware multiplier, DMA, a comparator, and an RTC module with alarm capabilities.

The MSP430F523x series microcontrollers include all of the peripherals of the MSP430F524x series except for the ADC.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
